Developers Core

An AI development company that treats production as the product.

Developers Core helps startups design and ship applied AI — retrieval systems, agents, vision pipelines, and LLM features — with the engineering discipline required after the first happy-path demo. UK-registered. Fixed-scope engagements.

Capability detail

01

Retrieval-augmented generation

Corpus design, chunking strategy, metadata filters, hybrid search, citation-first answers, refusal behaviour, and evaluation harnesses so quality does not silently regress.

  • Document ingestion pipelines
  • Jurisdiction / tenant isolation
  • Groundedness evals
  • Cost and latency budgets
02

Agents and tool-calling systems

Agents that call internal APIs with least privilege, durable state, human approval gates, and observability — not unbounded loops that email your customers by accident.

  • Tool schemas & auth boundaries
  • Workflow orchestration
  • Audit logs
  • Failure recovery
03

Computer vision & imaging

Detection, segmentation, and domain imaging pipelines — including healthcare-adjacent work where explainability and data handling are part of the product.

  • Model selection & fine-tuning
  • DICOM / domain I/O
  • Saliency / explainability
  • GPU inference paths
04

LLM features inside products

Copilots, extraction, classification, and automation wired into React/Node/Python codebases with product UX, rate limits, and monitoring.

  • Prompt + policy design
  • Streaming UX
  • Guardrails
  • A/B and feedback loops
05

Platform & cloud engineering

When AI work requires real infrastructure: APIs, queues, multi-region, IaC, and the unsexy reliability work that keeps customers.

  • FastAPI / Node services
  • AWS / Azure
  • Terraform
  • Observability
06

Product engineering

Full-stack delivery when the AI feature is useless without the surrounding product — auth, billing, dashboards, mobile, and admin tools.

  • Next.js / React Native
  • SaaS multi-tenant
  • Payments
  • Design systems

When AI projects should not start

There is no source of truth for the model to retrieve from — and no plan to create one.

Success is defined as ‘looks cool in a slide’ rather than a measurable user or ops outcome.

You need a research lab, not a product team (we will say so).

Budget only supports marketplace prototyping; production ownership is unfunded.

Scope an AI sprint

Feature Sprint engagements typically land between $4k–$8k over 3–4 weeks for a single production capability.
